Mathematics
1 answer:
faltersainse [42]2 years ago
4 0

Answer:

40 min is the answer

Step-by-step explanation:

To solve this we need to convert all the units into SI units

for ritu,

speed= 90km/hr

= 90 × 1km/ 1hour

= 90×1000/3600 m/s

= 25m/s

distance = 120×1000m

time = distance/ speed

= 120000/25

= 4800sec

= 4800/60min

= 80 min

for garima,

distance =120×1000m

speed = 60km/hr

= 60×1000/3600 m/s

=100/6 m/

time = 120000/(100÷6)

= 7200sec

= 7200÷60 min

= 120 min

time difference is 120-80 = 40 min

What is the value of x?<br><br> 6(−3−x)−2x=14<br><br> Enter your answer in the box.
olchik [2.2K]
For this we would first simplify using order of operations.
6(-3-x) - 2x = 14 ------> Distribute
-18 -6x - 2x = 14 ------> Combine Like Terms
-8x - 18 = 14 Now we want to isolate x!
-8x - 18 = 14 ------> Add 18 to both sides.
-8x = 32 ------> Divide both sides by -8.
x = -4
Hope this helps!
