Peter drives his van a distance of 54 km. He leaves the depot at 10:55 and arrives back at 12:38. Calculate his average speed

OLga [1]

Answer:

31.46 km/hr to the nearest 100th

Step-by-step explanation:

10:55 to 11:00 is 5 min

11:00 to 12:00 is 60 min

12:00 to 12:38 is 38 min

That's 5 + 60 + 38 = 103 min = 103/60 hr. = t

d = rt

54 = 103/60(r)

r = 54(60)/103 =31.46 km/hr to the nearest 100th

Which choice is equivalent to the quotient below? √64/√4<br>a. √2<br>b. √4/4<br>c. √8/2<br>d. 4

Ksju [112]

Step-by-step explanation:

you did not even try a calculator to find the result ?

64 is 8×8 or 8².

so, sqrt(64) = 8.

similarly for 4 :

4 is 2×2 or 2².

so, sqrt(4) = 2

so,

sqrt(64)/ sqrt(4) = 8 / 2 = 4

so, d. is the right answer.
