Question

A train travels 650 km in 5 hours. How much distance will it cover in 12 hours?
How long will it take to travel 975 km.?​

Answer 1

Answer:

Distance  covered in 12 hours is 1560 km

Time taken to travel 975 km is 7 hours 30 minutes

Step-by-step explanation:

Speed of the train = Distance traveled / time taken

Speed = 650 / 5

Speed = 130 km /hr

If train moves in 130 km/hr,  distance covered in 12 hours is

Speed= distance/ time

130= distance / 12

Distance = 130 x 12 = 1560 km

Hence distance  covered in 12 hours is 1560 km

Time taken to travel 975 km is

Speed= distance/ time

130= 975 / time

Time= 975 / 130

Time = 7 hours 30 minutes

thus time taken to travel 975 km is 7 hours 30 minutes

Answer 2

Step-by-step explanation:

in first case

d= 650km

T=5h

then, s=d/T

s=650km/5h

s=130kmph

then, in 12 h

s=130kmph

t=12h

now, s=d/t

130kmph=d/12h

130kmph.12h=d

1560km

now for time

s =130kmph

d=975km

then, s=d/t

130kmph=975km/t

130kmph.t=975km

t=975kmh/130km

t=7.5h
