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

Answer:

$\boxed{Distance = 3.33\ km}$

Step-by-step 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

Answer 2

Answer:

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

Step-by-step explanation:

Using the given formula,

estimated distance = v.t  = velocity * time,

velocity = 5 km/h

time = 40 minutes = $\frac{40}{60}$ hours = $\frac{2}{3}$  hours

Therefore

distance = 5 km/h * $\frac{2}{3}$  hours = 10/3 km

= 3.33 km approximately
