Question

The formula for the distance travelled over time t and at an average speed v is v⋅t. Amit ran for 40 minutes at a speed of about 5 kilometres per hour. What calculation will give us the estimated distance Amit ran in kilometres?

Answer 1

3 1/3 km or 3.33 km (to the hundredth)

Explanation:

Using the given formula,

estimated distance = v.t = velocity * time,

velocity = 5 km/h

time = 40 minutes =
`(40)/(60)` hours =
`(2)/(3)` hours

Therefore

distance = 5 km/h *
`(2)/(3)` hours = 10/3 km

= 3.33 km approximately

Answer 2

`\boxed{Distance = 3.33\ km}`

Explanation:

Given:

Time = t = 40 min = 40/60 = 0.67 hours

Speed = v = 5 km/hr

Required:

Distance = S = ?

Formula:

Distance = Speed × Time

Solution:

Distance = 5 × 0.67

Distance = 3.33 km
