Question

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

Answer 1

Answer:

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
