Question

A cyclist rides her bike at a rate of 9 kilometers per hour. What is the rate in kilometers per minute? How many kilometers will the cyclist travel in 2 minutes

Answer 1

Rate(in km/min) = 0.15 km/min

Distance traveled in 2 mins = 0.3 km

Explanation:

Rate = 9 km/hr

1 hr = 60 mins

In 60 minutes, the cyclist rides 9 km

in 1 minute, the cyclist will ride 9/60 km

Therefore, the rate in km/min = 9/60 km/min

Rate(in km/min) = 0.15 km/min

Since the cyclist rides 0.15 km in 1 min,

In 2 mins, the cyclist will ride 0.15 * 2 km = 0.3 km

Distance traveled in 2 mins = 0.3 km

Answer 2

Answer: 0.15km/min and 0.3km in 2 mins

Explanation:

Given Data:

Cyclists speed = 9km/hr

1. Some traveling 60 km/h is traveling one km/min

60/60= 1 km/min

Rate in km/min

= 9km/hr / 60min

= 3/20 km/min

= 0.15 km/min

Kilometers travelled in 2mins

= 2 / 60

= 1 / 30

= 9km/hr * 1 / 30

= 9 / 30

= 0.3 km in 2mins
