Aman walks down the road for half an hour at an average speed of 3 miles per hour. he waits 10 minutes for a bus, which brings him back to his starting point at 3: 15. if the man began his walk at 2: 25 the same afternoon, what was his average speed of the bus

9 mph

Step-by-step explanation:

Half an hour=30 minutes             at a speed of 3 miles per hour

So he walks 1.5 miles

2:25 to 3:15 is 50 minutes

30 + 10=40

50 - 40=10

so the bus goes 10 minutes travelling 1.5 miles

as there are 6 x 10 minutes in an hour you times 1.5 miles by 6 to find out the mile per hour which is 9
