depot base 141 km away. The tank travels at an average speed of 24
km/h. An emergency humvee from the depot heads out to meet the

You can put this solution on YOUR website!
You can think of this as 1 of them standing still
and the other heading toward the stationary one
at the sum of their speeds, so
+141+=+%2824+%2B+70%29%2At+
+t+=+141+%2F+94+
+t+=+1.5+
It will take an hour and a half for them to meet
