Answer:
The equations that are true are
B
C
E
Step-by-step explanation:
A) States that 0 + 451 = 0, but that is not true because...
0 + 451 = 451
B) States that 130 + 210 = 210 + 130, and that is true because...
130 + 210 = 210 + 130
340 = 340
C) States that (127 + 80) + 250 = 127 + (80 + 250), and it is true because...
(127 + 80) + 250 = 127 + (80 + 250)
127 + 80 + 250 = 127 + 80 + 250
457 = 457
D) States that (123 + 57) + 180 = 153 + (87 + 180), but that is not true because...
(123 + 57) + 180 = 153 + (87 + 180)
123 + 57 + 180 = 153 + 87 + 180
360 = 420 (but this does not make sence)
E) States that 497 + 0 = 497, and it is true because...
497 + 0 = 497
497 = 497
Time taken by Daniel to catch up with Frank is 4 minutes.
Step-by-step explanation:
The question is on relative speed; speed of a moving object with respect to another.
The two cars are travelling in the same direction at different speeds thus;
Relative speed = speed of Daniel - speed of Frank = 50-45= 5 mph
The time which the two meet = distance/ relative speed
Distance = 1/3 miles, which equals 0.33 miles
Time taken by Daniel to catch up with Frank is = 0.33/5 =0.066 hours = 4 minutes.
