Question #ab60e

1 Answer

Nov 15, 2016

In the morning, they travelled #105# miles.

Explanation:

If we represent the distance travelled in the morning as #x#, the distance travelled in the afternoon will be #3x#, and we can write an equation:

#x+3x=420#

#4x=420#

Divide both sides by #4#.

#x=420/4#

#x=105#
