Question

ek car travels first 30 kilometre in 1 hour and next 40 km in 2 hours calculate the average speed of the car​

Answer 1

Explanation:

The formula for average speed is total distance divided by total time

●Total distance = 30km + 40km = 70km

●total time = 1hr + 2hr =3hr

◆Average speed = 70km ÷ 3hr

= 23.33kmph

Answer 2

Concept:

average speed = total distance / total time

Given:

The vehicle  travels the first 30 kilometers in 1 hour

The vehicle travels the next 40 km in 2 hours

Find:

calculate the average speed of the car​

Answer:

$23.334\frac{km}{hour}$

Explanation:

The vehicle  travels the first 30 kilometers in 1 hour

The vehicle travels the next 40 km in 2 hours

average speed = total distance / total time

total distance $= (30 + 40)km = 70 km$

total time $= (1+2) hour = 3 hour$

average speed = total distance / total time = $\frac{70km}{3hour}$

average speed = total distance / total time =$23.334\frac{km}{hour}$

Hence the average speed of the car​    $23.334\frac{km}{hour}$ .
