Question

A train travels 112 km in 1 hour 30 minutes at a certain speed. How many kilometres it will travel in 4 hours 45 minutes at the same speed?

Plz send answers accordingly to direct and inverse proportion

Answer 1

1hr 30 min = 90 min

4hr 45 min = 285 min

✅ 90 min ➡ 112km

✅ 1 min ➡ 112/90 km .

✅ 285 min ➡ 112 × 285/90 km

= 354.66 km

Answer 2

Answer:

Distance travelled in 1 hour 30 minutes = 112 Km

Distance travelled in 4 hour 45 km is = ?

So , Distance = v × t

velocity = d / t

So , V1 = 112 km / 90 min

= 1.24

So , D2 = v × t

= 1.24 Km/min × 285 min

= 352.16 Km

So , it will cover 352.16 km in 4 hours 45 min
