Question

A car travels a distance of 258 km in 3 hours 35 minutes. What is the speed of the car?​

Answer 1

Answer:

Speed of the car = 72 km/h

Step-by-step explanation:

Distance Covered= 258 km

Time taken = 3 hours 35 mins

                   = 3 + 35/60

                   = 3 + 7/12

                   = (36 + 7)/12

                   = 43/12

Speed = Distance covered ÷ Time taken

           = 258 ÷ 43/12

           = 258*12/43

           =72 km/h

Answer 2

Answer :

➥ The speed of the car = 72 km/hr

Given :

➤ Distance travelled by a car (d) = 258 km

➤ Time taken by a car (t) = 3 hours 25 minutes

To Find :

➤ Speed of a car (s) = ?

Solution :

To find the speed of the car first we need to convert the time taken 3 hours 25 minutes into hour, then after we find the speed of the car from the formula of Speed.

◈ Time taken (t) = 3 hours 25 minutes 3 + 35/60 = 43/12 hr

Now ,

As we know that

$\tt{:\implies Speed = \dfrac{Distance}{Time \: taken}}$

$\tt{:\implies Speed = \dfrac{258}{ \dfrac{43}{12} }}$

$\tt{:\implies Speed = 258 \times \dfrac{12}{43} }$

$\tt{:\implies Speed = 6 \times 12}$

$\bf{:\implies \underline{\:\:\underline{\red{\:\: Speed = 72 \: km/hr\:\:}}\:\:}}$

║ Hence, the speed of the car is 72 km/hr️. ║
