Question

Distance = speed × time = 225km = speed × 2.5hrs

Answer 1

Formula:
Distance = speed × time

Given
Distance = 225 km
Time = 2.5 hrs

Find speed:

D = s × t
225 = s × 2.5
Divide by 2.5 on either sides to isolate s


`(225)/(2.5)` =
`(2.5s)/(2.5)`
2.5 and 2.5 cancels out

90 = s
speed = 90 km/hr (as the given were km and hr)

Answer 2

Speed = (225/2.5) km/hour Speed = 90 km/hour
