(16) Tom took a 1900-mile trip by bus and plane. The bus averaged 60

miles per hour and the plane averaged 700 miles per hour. If the trip

took 5 hours, how many miles did Tom travel by bus? [150 miles]math

1 answer

If he traveled x miles by bus, then he went 1900-x by plane.

Since time = distance/speed,

x/60 + (1900-x)/700 = 5
