Question

The speed of an ant is (2t + 10) and after travelling for t minutes, it covers a distance of 12m. find t.

Answer 1

by solving the equation u get u r answer
60t ka square +5t - 6 = 0

Answer 2

Answer:

1 minute

Step-by-step explanation:

Speed of ant = 2t+10

Time = t minutes

Distance = 12 m

Since we know that $Distance = speed \times time$

So,$12= (2t+10)\times t$

$12= 2t^2+10t$

$6= t^2+5t$

$t^2+5t-6=0$

$t^2+6t-t-6=0$

$t(t+6)-1(t+6)=0$

$(t+6)(t-1)=0$

t = -6,1

Since time cannot be negative so, t = 1

Hence the value of t is 1 minute
