Answer:
Step-by-step explanation:
<u>Let the score is x. The average is:</u>
- (83 + 56 + 94 + x)/4 = 82
- x + 233 = 4*82
- x = 328 - 233
- x = 95
When it says 4x4 and 12x2 does that mean it’s squared or multiplied by those?
Answer:
22 hours (B)
Step-by-step explanation:
John's velocity = 55mph
Sally's velocity = 65mph
John's time taken = x
Sally's time taken = x - 4
since they must cover the same distance.
and, distance = vel × time
Sally's vel × time = John's vel × time
55x = 65(x-4)
55x = 65x - 220
-10x = -220
x = 22 hours.
Therefore, Sally catches up after 22 hours
