Question

with a uniform speed a Car Covers The distance in 8 hours.had the same speed been increased by 4 kmph . the same distance could have been covered in 7.5 hours . what is the distance Covered​

Answer 1

Step-by-step explanation:

Let the distance be x Km. Then,

$= > \frac{x}{7 \frac{1}{2} } - \frac{x}{8} = 4$

$= > \frac{2x}{15} - \frac{x}{8} = 4$

$= > x = 480km$

Answer 2

Answer:Distance is 60 km

Step-by-step explanation:

Let as assume uniform speed to be x

speed(s)=distance(d)/time(t)

speed=x

d=s x t

d=8x (as 8 hours is given)-1

now speed is increase by 4 kmph

d=(x+8) x 7.5 (new time is 7.5 hours)02

subs 1 in 2

8x=30+7.5x

0.5x=30

x=60km
