Speed of Morris is 47.95 mph
Step-by-step explanation:
- Step 1: Convert 3 feet per second to miles per hour.
⇒ 3 ft/s = 3/1.467 mph (∵ 1 mph = 1.467 ft/s)
= 2.05 mph
- Step 2: Find the speed of Morris.
Speed of Morris = 50 mph - 2.05 mph = 47.95 mph
Well, since you have the value of b, the first thing you want to do is substitute that value in for b.
5a - 10(3) = 45
10*3 = 30
5a - 30 = 45
Now, to get the variable by itself (a) you have to + 30 because you have to reverse the subtraction.
5a = 75
Now, you divide by 5 to finish getting a by itself.
a = 15
Hope this helps!
