A bus leaves Denver 40 minutes before a second bus.

The first bus travels at 45 mph, and the second bus travels 63 mph.

How long does it take the 2nd bus to catch up to the first bus?

a) Let
the time the first bus spends traveling. Write the equation you would use to find this time.


b)
2.6
hours after the first bus left, the second bus catches up. (Round to one decimal place.)

c) Convert your time from b) to hours to hours and minutes:
2
Correct hours and
36
minutes

a) Let t be the time the first bus spends traveling. The equation that can be used to find this time is t + 40 minutes = t.

b) If 2.6 hours after the first bus left, the second bus catches up, then the time it took for the second bus to catch up is 2.6 hours.

c) Converting 2.6 hours to hours and minutes, we have 2 hours and 36 minutes.
