Question

The car is moving with a speed of 60km/hr.travels y km in x hours . Represent this situation as a linear equation of two variables Find the distance travelled when time 5 hours and also in 10 hours

Answer 1

Answer:

Step-by-step explanation:

let the distance travelled in 5h and 10h be x & y respectively.

By Unitary Method:

Time Taken (hours)                            Distance(km)

        1                                                       60

        5                                                        x

1/5 = 60/x

By cross multiplication

x = 60x5

x = 300km

--------------------------------------------------------------------------------------------

Time Taken (hours)                            Distance(km)

        1                                                       60

        10                                                        y

1/10 = 60/y

By cross multiplication

y = 60x10

y = 600km

Answer 2

Answer:

y = 60x

Step-by-step explanation:

Dist. = Speed × time

y=60×x

y=6ox

(i) time = x= 5hrs

so dist=y becomes

y=60× 5

y= 300km

(ii)similarly

if x= 10

then y= 600km
