Question

a bus leaves station A at 9:00 a.m. and ahead towards 220 miles away an hour later another bus leaves station A it travels twice as last as the first bus arrives in the city 2 hrs ahead of the first bus find speed of the bus

Answer 1

• speed of the first bus: 36 2/3 miles per hour
• speed of the second bus: 73 1/3 miles per hour

Explanation:

The second bus travels twice as fast, so will take half the time of the first bus. The second bus takes 3 hours less time, so that is half the time of the first bus.

The first bus's speed is (220 mi)/(6 h) = 36 2/3 mph.

The second bus's speed is twice that: 73 1/3 mph.
