Question

Sam takes 1/3 hour to walk 1 km. he walks at the same rate. how many km will he walk in 4/5 of an hour

Answer 1

Speed of Sam = Distance / Time
Here, Distance = 1 Km
Time = 1/3 hour

Substitute the values, in the formula:
Speed = 1 / 1/3 = 3 Km/h

Now, In next situation, Speed = 3 Km/h
& Time = 4/5 hour.

Substitute the values, in the same formula:
Distance = Speed × Time
D = 3 * 4/5
D = 12/5 = 2.4 Km

In short, Final answer of your question would be 2.4 Km

Hope this helps!

Answer 2

1\3 × 5 = 5\15 km per hour
4\5 × 3 = 12\15 km
He will walk 2.4 km in 4\5ths of an hour
