The lava from a volcano can travel up to 100 km/hr if a village is located 3.6 mi from the volcano how many minutes will it take the lava to reach the village

3.47 minutes

Explanation:

First we must convert the distance travelled from miles to kilometres

Since;

1 mile = 1.6093 km

3.6 miles = 3.6 * 1.6093 km = 5.79 Km

Substitute this into

Speed = distance / time

Speed = 100Kmhr-1

Distance = 5.79 Km

Time = the unknown

Time = distance/speed

Time = 5.79/100

Time = 0.0579 hours

Since;

60 minutes make one hour

x minutes make 0.0579 hours

x = 60 * 0.0579 hours

x = 3.47 minutes
