Question

A motorbike races at a speed of 80 km/hr. What distance will it cover in 90 minutes​

Answer 1

Answer:Speed = Distance / Time

80km/h = Distance / (90/60)hr

Distance = 80*(90/60) km

= 120 km

So, 120 km will cover in 90 minutes.

2) Speed = Distance / Time

80km/h = 240 km / Time

Time = 240 km / (80 km/h)

= 3 hr

= (3*60) minutes

= 180 minutes

So, 180 minutes will take to travel 240 km
