Answer:
140+d = 192
d = 52
Step-by-step explanation:
the weight of the vet plus the god = total weight
140+d = 192
d = 192 - 140
d = 52
You need to bring them to a common denominator by multiplying the numbers below and above the line by the denominator of the other:
and the other one will be
when we calculate we have
60/105 and the other number is 56/106.
now we can add them:
(60+56)/105=116/105= 1 and 11/105 or 1.104....
Time=(distance)/(speed)
speed=55 mi/hr
Total distance=440 miles
Distance covered=275 miles
remaining distance=440-275=165 miles
Time taken to cover the remaining distance will be:
time=165/55=3 hours
Total time taken to travel=440/55=8 hours
if we are to use the equation given by:
55h+275=440
time taken will be found by solving for h, thus we shall have:
55h=440-275
55h=165
h=165/55
h=3 hours
Answer: 3 hours
