1.) Fuel Efficiency: On Friday, you left for a weekend camping trip with 110 miles on the odometer and 14.5 gallons of gas in the tank of your car. When you returned on Sunday, the odometer read 299 miles and you still had 7.5 gallons of gas left. What was the fuel efficiency of your car on this trip?
2.) Production Rate: When you stared your shift at 7:00A.M., 120 steel valves had already been machined and were ready for assembly. At 3:00P.M., your shift ended and 424 steel valves were now completed and ready for assembly. The target production rate is 36 steel valves per hour. What was the production rate for your shift? Would your supervisor be satisfied with the work pace?
1)
299 - 110 = 189 miles
14.5 - 7.5 = 7 gallons
189 / 7 = ______ mpg
2)
I'll be glad to check your answer.
ok for the second one Idek what I did. But the answer I got was 2. I am so confused.!!!! HELP
424 - 120 = ?
Divide your answer by 8 hours.
So the answer is 8 production rate. So the supervisor would be satisfied then?
I meant 38
Right.
To calculate the fuel efficiency of your car on the camping trip, you need to determine the distance traveled and the amount of fuel consumed.
1.) Calculate the distance traveled:
- Subtract the initial reading on Friday (110 miles) from the final reading on Sunday (299 miles).
299 miles - 110 miles = 189 miles
2.) Calculate the fuel consumed:
- Subtract the remaining fuel on Sunday (7.5 gallons) from the initial amount of fuel on Friday (14.5 gallons).
14.5 gallons - 7.5 gallons = 7 gallons
3.) Calculate the fuel efficiency:
- Divide the distance traveled (189 miles) by the amount of fuel consumed (7 gallons).
189 miles / 7 gallons = 27 miles per gallon (mpg)
Therefore, the fuel efficiency of your car on this trip was 27 mpg.
To calculate the production rate for your shift, you need to determine the number of steel valves produced and the duration of your shift.
1.) Calculate the number of steel valves produced:
- Subtract the initial count at the start of your shift (120 steel valves) from the count at the end of your shift (424 steel valves).
424 steel valves - 120 steel valves = 304 steel valves
2.) Calculate the duration of your shift:
- Subtract the start time (7:00 A.M.) from the end time (3:00 P.M.).
3:00 P.M. - 7:00 A.M. = 8 hours
3.) Calculate the production rate:
- Divide the number of steel valves produced (304 steel valves) by the duration of your shift in hours (8 hours).
304 steel valves / 8 hours = 38 steel valves per hour
The production rate for your shift was 38 steel valves per hour. Given that the target production rate is 36 steel valves per hour, your supervisor should be satisfied with the work pace as it exceeded the target rate.
