Question

a car is running from a to b at a speed of 40 km/h .it covered half of the total distance in 2 h.then distance between a and b is​

Answer 1

Step-by-step explanation:

A car travels a certain distance at 24 km/h and comes back at 36 km/h. What is the average speed of the car for the total journey.?

Your newborn may be vulnerable to these 6 serious diseases.

Formula for average speed is = total distance/total time

now, let the distance be = x (for each side)

then total distance = x+x = 2x

we know that ,distance = speed * time

then, time = distance/speed

time taken to travel first distance = x/24

time taken to come back = x/36

total time = x/24 + x/36

now put this figures in the formula of average speed and we will get = 2x / (x/24 + x/36)

solve the equation by taking L.C.M

and we will get average speed which is

28.8km/hr

Answer 2

Answer:

distance = 80 km

Step-by-step explanation:

a car is running from a to b speed = 40 km/h

a car is running half of total distance = 2h

we can find  distance

so, use the formula

distance = speed × time

distance = 40 × 2

distance = 80 km
