Step-by-step explanation:
Answer:
<h2>Frank speed = 37mi/h</h2><h2>Gregory speed = 59mi/hr</h2>
Step-by-step explanation:
Let the speed of Frank be x and speed of Gregory be y. If Gregory drives 22 miles per hour faster than Frank, then y = 22+x. SInce they they are 216miles apart after 2.25 hours,
Speed = Distance/Time
Total time travelled by them = 2.25hours
Total distance = 216 hours
Total speed = x+y = x+22+x
Substituting this parameters into the formula given to get x we will have;
x+22+x = 216/2.25
2x+22 = 96
2x = 96-22
2x = 74
x = 74/2
x = 37
<em>Hence the speed of Frank is 37miles per hour while that of gregory is 37+22 = 59miles/hour</em>
1/4 * x + 1/4 * 4
(the * are multiplication signs)
